In order to handle the problem that puncture patterns will change position distribution of original information bits and frozen in polar codes, which affects performance codes further, a minimum row weight spectrum based construction algorithm (called PA-MRWP) is proposed this paper.The calculates generator matrix sorts ascending first.Next, positions with are selected as initial positions.If rows same cannot all be punctured, auxiliary scheme used.In sub-channels weight, corresponding polarized higher reliability construct vector, calculated on spectrum.It actually two-step selection strategy, (MRWP) used for primary adjustment.Simulation results show that, compared worst quality (WQP) algorithm, PA-MRWP Gaussian approximation-aided (GA-MRWP) provide gains about 0.46 dB 0.29 at bit error rate (BER) 4 10 -, respectively when code length 400 N = , 1 / 2 R .In addition, algorithms improve BER significantly respect quasi-uniform (QUP) algorithm.
